Abstract
A discharge circuit, an image forming apparatus having the discharge circuit, and a power-supply unit are disclosed to minimize a standby power generated in a standby mode and improve a discharging speed of a capacitor charged with electricity by the AC power in a power off mode. The discharge circuit connected between AC power input lines receiving an AC power includes a first resistor and a first switch element connected in series between the AC power lines, and a second resistor and a second switch element which are connected in series between the AC power lines, turn off the first switching element upon receiving an electric current during supply of the AC power, and turn on the first switching element in response to cutoff of the AC power to discharge the first capacitor.
